What the packet contains
Sections in FEMA checklist order; each heading names the review item its tables support. Full tables are in the downloads above.
Supports FEMA checklist item B1-a Hazard identification
14 of the 18 National Risk Index hazards apply here.
Not applicable to this county per NRI, with no federal declaration and no Storm Events record since 1996: avalanche, coastal flooding, tsunami and volcanic activity. That is the evidence for leaving them out of the plan.
Highest expected annual loss (NRI, modeled): Inland Flooding, Tornado and Earthquake.
Not covered by NRI (local data needed): dam failure (incl. upstream dams); levee failure; flash flood as its own subtype; ice jams; debris flows; erosion (riverine and coastal); land subsidence and sinkholes; expansive soils.
The state hazard mitigation plan also lists hazards for this county; FEMA asks the plan to explain any hazard it leaves out.
Supports FEMA checklist item B1-b Hazard location
- Cold Wave, Drought, Hail, Heat Wave, Ice Storm, Lightning, Strong Wind and Winter Weather: affects the whole county; national data give no location within it.
- Earthquake, Hurricane, Landslide, Tornado and Wildfire vary within the county; the packet lists the highest-rated census tracts for each.
- Inland Flooding: the FEMA Flood Insurance Rate Map (FIRM) is the required location source for flooding. See the FEMA Flood Map Service Center (https://msc.fema.gov) for this county.
Supports FEMA checklist item B1-c Hazard extent
Storm Events records for 13 of the 21 NOAA event-type groups mapped to the 18 hazards, with the scale, observed range and worst recorded event for each; the others say which local data are needed.
Worst recorded tornado, hail and thunderstorm wind (the three event types on record since the 1950s; the packet has every group):
- Hail: 2.75 in hail, 2025-05-16; same size also recorded on 1993-05-05, 2000-04-16, 2000-05-23, 2006-04-30, 2014-08-19
- Thunderstorm Wind: 96 kt (110 mph), measurement type not recorded, Thunderstorm Wind, 1998-10-05
- Tornado: F3 tornado, 2002-04-27, 4 mi within this county, 200 yd wide, $4,000,000 property; crops not reported (2002 dollars), 1 direct death, 16 direct injuries
Supports FEMA checklist item B1-d Previous occurrences
Federal declarations for this area: 28 declarations covering 23 separate hazard incidents counted in this packet; each with type, dates and county Public Assistance dollars.
New since the last plan (approved 2025-05-16): DR-4939-MO, DR-4872-MO and DR-4867-MO.
4 statewide declarations listed separately.
Hazards with no Storm Events record and no federal declaration are stated as such (6 of 18).
Storm Events history: 718 records (notable ones in the PDF, all of them in the Excel file).
Supports FEMA checklist item B1-e Probability of future events
FEMA annualized frequency (modeled) for each hazard, with a descriptor from a scale defined in the packet.
- Highly likely: Hail, Heat Wave, Landslide, Lightning, Strong Wind and Winter Weather
- Likely: Cold Wave, Drought, Ice Storm, Inland Flooding and Tornado
- Possible: Hurricane
- Unlikely: Earthquake and Wildfire
Historical frequency by intensity band (tornado, hail, wind): 9 bands from Storm Events.
Supports FEMA checklist item B1-f Hazards that vary across jurisdictions
Range of census tract risk scores within the area for 14 of the 18 hazards (3 tracts; rated tracts only).
1 jurisdiction: plan clock, repeat-flood count, Public Assistance dollars and event records naming the place (starting figures from federal data).
County Public Assistance in B1-d also includes applicants filed under the county that are not matched to a jurisdiction row here (for example county offices and boards filed under their own names, such as a sheriff's office or a conservation board, and state agencies, special districts and nonprofits), so the jurisdiction rows add up to less.
Supports FEMA checklist items B2-a and B2-b Vulnerability and potential impacts
The packet's table gives county-level starting figures; the plan describes impacts for each jurisdiction and its own assets.
Storm Events damage since 2025-05-16: $16,000 in county-coded records (5 records); $3,000 reported for the zone (14 zone records). Data through 2026-06-30; nominal dollars.
Local data needed
To gather:
- Critical facilities and lifelines per hazard
- A problem statement per jurisdiction per hazard
- Changes in development in hazard-prone areas since the last approval, or a statement of none (E1-a)
- Future assets
Supports FEMA checklist item B2-a Vulnerability (county context)
Population 10,557; building value $2,509,256,349 and agriculture value $41,346,533 (total, not at risk).
National Risk Index rating Very Low; social vulnerability Relatively Low; community resilience Relatively Low.
Supports FEMA checklist item B2-c Repetitive loss properties
